Zakharia 12:9

12:9 So on that day I will set out to destroy all the nations ¹  that come against Jerusalem.”

Zakharia 14:6

14:6 On that day there will be no light – the sources of light in the heavens will congeal. ² 

[12:9]  ¹ tn Or “peoples.”

[14:6]  ² tn Heb “the splendid will congeal.” This difficult phrase (MT יְקָרוֹת יְקִפָּאוֹן, yÿqarot yÿqippa’on) is not clarified by the LXX which presupposes וְקָרוּת וְקִפָּאוֹן (vÿqarut vÿqippa’on, “and cold and ice,” a reading followed by NAB, NIV, NCV, NRSV, TEV). Besides the fact that cold and ice do not necessarily follow the absence of light, the idea here is that day will be night and night day. The heavenly sources of light “freeze up” as it were, and refuse to shine.
